HistoryWidget::resizeEvent() can start taking TabbedSelector from
TabbedPanel which will call QWidget::render() which can call again
HistoryWidget::resizeEvent() from sendPendingMoveAndResizeEvents().
Use a separate flag for _tabbedSection to prevent recursion there.
Sometimes Open Sans Semibold fails to load properly on the latest
Windows Creators Update. In that case try to load Segoe UI instead.
An attempt to fix#3276.
If some RPC responses and MTP updates are received together a fake
requestId in the negative range was used and that way updates were
processed before responses.
That could lead to an incorrect "out" message flag when sending
messages to supergroups, because a broadcast update about the new
message without "out" flag was handled before the request response.
Now a separate response map and updates list are used and responses
are handled always before the updates.
Also add some more decoders in ffmpeg configuration (wav).
Also stop audio device restart on PKEY_AudioEndpoint changes.
Also deduce channel layout from channel count in ffmpeg loaders.
If notifications are muted no one from official apps play sound.
So there is no need to turn the sound off, otherwise if you enable
the notifications from a different app the sound stays off.
Enable the sound (change to "default") when turning notifications on.
Regression was introduced in 835b1801bc.
We need to destroy all FileLoader instances before destroying the
Downloader instance, because they hold pointers to it and call its
methods in destructor if they need to cancel some MTP requests.
Sometimes NSUserNotificationCenter -deliveredNotifications method call
freezes for a long time, so now we use it only in a separate thread and
we group all the requests for clearing while another clearing is done.
Don't deactivate the application when the main window is hidden.
Such behavior provides some unwanted windows reordering in the
current workspace when the window is hidden by Cmd+W.
Ignore app activation by applicationDidBecomeActive: notification
for a short period of time after a user notification for other app
instance was received (the system sends them sometimes and the main
window is shown + activated for a wrong instance of the application).
